چکیده
Abstract In this paper, a Reflective Semiconductor Optical Amplifier based, Radio-over-Fibre access network configuration has been proposed to feed future millimeter-wave radio systems. The system architecture combines several approaches overcome the challenges of signal transmission. semiconductor optical amplifier modulator realizes colorless and relatively cost-effective Remote Antenna Unit. same carrier is used for both downlink uplink. single-sideband modulation at downlink, which robust against chromatic dispersion, but complex realization format not possible intermediate frequency transmission applied uplink direction, required local oscillator originates from central station. critical element reflective amplifier, as it compensates loss works an external intensity modulator. operation modeled by multisection rate wave equation-based description. amplification behaviors available are also measured. experimental work validated quality versus bias current input power. Finally, simulation was realized. power budgets were balanced, optimal values coupling RSOA have selected.

Effect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملMacrodiversity performance in the uplink of WCDMA with radio over fibre access network
In this paper, the performance of the uplink of a WCDMA Radio over Fibre access network during Macrodiversity mode is investigated. We propose a novel Macrodiversity scheme in the uplink, based on Maximum Ratio Combining (MRC) of the received symbols by different BS receivers of a WCDMA mobile cellular system with RoF. Our simulation results demonstrate that, for a given service, the coverage e...
